      I have a 2022 refreshed Silverado LTZ and have an apparent ghost in my left front signal light. From time to time when I turn it on it will flash three or four times normally then go into hyper mode and throw a warning on the screen saying “check left front turn lamp”. The light is in fact not working. Took it to the dealer but of course it bothered on the way over but corrected itself when I got there so they found nothing. When I left within 20 minutes it happened again. It is so intermittent it would do no good to turn around and go back because it would be working fine by the time I got there. Sounds like a loose connection or bad ground somewhere but almost impossible to find. Anyone else have this issue or thoughts on this??
